A wireless communication device includes a first wireless communication circuit, a first terminal, and a processor. The first wireless communication circuit executes receiving first image information by a first wireless communication method, and transmitting wireless connection destination information. The processor executes adding information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is coupled to a display device, and not adding the information representing that communication is performed by the first wireless communication method to the wireless connection destination information, when the first terminal is not coupled to the display device.

2. The wireless communication device according to claim 1, wherein the first wireless communication circuit maintains communication by the first wireless communication method when a hot-plug-detect signal from the first terminal changes from on to off while communication by the first wireless communication method is being executed.
This invention relates to wireless communication devices designed to maintain stable connections during hot-plug events. The problem addressed is the disruption of wireless communication when a connected terminal device is physically removed or disconnected, which can cause abrupt termination of data transfer. The invention provides a solution by ensuring continuous communication even when a hot-plug-detect signal from the terminal changes from an active to an inactive state during ongoing wireless communication. The wireless communication device includes a first wireless communication circuit configured to establish and maintain communication using a first wireless communication method, such as USB Power Delivery (USB PD) or another high-speed protocol. The device also includes a second wireless communication circuit for alternative communication methods, such as Bluetooth or Wi-Fi, to ensure redundancy. The key feature is that the first wireless communication circuit is designed to persist communication when the hot-plug-detect signal transitions from on to off, preventing data loss or connection drops during terminal disconnection. This is particularly useful in scenarios where physical disconnection is expected, such as in portable or wearable devices, ensuring seamless data transfer without manual re-connection. The invention enhances reliability in wireless communication systems by mitigating disruptions caused by physical disconnections.
